Sodium silicate sand casting is soluble in water in various amounts. A more common name for sodium silicate is water glass, which is used in iron or steel sand casting. The water glass works as a binder of the sand. Using sodium silicate sand binder allows the rapid production of a strong sodium silicate casting mold, by CO2 through the mixture of sand and sodium silicate in the mold, which hardens it almost instantly. The process is called sodium silicate co2 molding. Sodium silicate is a generic name for chemical compounds with the formula Na2SiO3. This material is generally colorless transparent solids, or in white powder, non-toxic and non-inflammable.

What is sodium silicate Moulding?

Though in most conditions, sodium silicate is one of the types of sand casting and considered to be applied in sodium silicate sand casting. Actually it also could be applied in the sand casting. Besides, sodium silicate sand casting is more suitable to make large and complex structures with an even better surface finish and fewer defects.
